Aphasia and apraxia are two major neuropsychological syndromes that in most cases are caused by injuries in the left cerebral hemisphere. Clinical studies have revealed a double dissociation between aphasia and apraxia, and a strong correlation in their cerebral lateralization. These clinical observations suggest that aphasia and apraxia are independent syndromes. On the other hand, there are m...

The relationship between constructional apraxia and body scheme disorders and failure of post-cerebral vascular accident (CVA) patients to achieve independence in upper extremity dressing was investigatged in this study. One hundred and one subjects with right- and left-CVA were given tests that measured body scheme dysfunction and constructional apraxia on admission to an inpatient rehabilitat...

Limb apraxia is a common disorder of skilled, purposive movement that is frequently associated with stroke and degenerative diseases such as Alzheimer disease. Despite evidence that several types of limb apraxia significantly impact functional abilities, surprisingly few studies have focused on development of treatment paradigms. Additionally, although the most disabling types of apraxia reflec...

OBJECTIVES The study aimed at addressing the issue of the precise nature of gait apraxia and the cerebral dysfunction responsible for it. METHODS The case of a patient, affected by a bilateral infarction limited to a portion of the anterior cerebral artery territory is reported. The patient's ability to walk was formally assessed by means of a new standardised test. RESULTS Due to an anomal...

To cite: Cassidy A. Pract Neurol 2016;16:317–322. INTRODUCTION Neurologists are familiar with the standard definition of apraxia: ‘an inability to perform a motor task that cannot be adequately explained by motor weakness, sensory loss or a lack of understanding’. Being a definition of exclusion, this has led to a bewildering number of motor disorders being described as forms of apraxia, despit...

BACKGROUND Spasmus nutans and congenital ocular motor apraxia share clinical characteristics. However, their development in a patient with cerebellar vermian hypoplasia has not been previously described. OBJECTIVE To report spasmus nutans and congenital ocular motor apraxia in a child with cerebellar vermian hypoplasia. DESIGN Case report. SETTING Tertiary-care hospital. Patient A 7-year-...
